Title:
LASER PROBE CLASSIFICATION METHOD AND DEVICE CAPABLE OF AUTOMATICALLY SELECTING SPECTRAL LINES ON BASIS OF IMAGE FEATURES
Document Type and Number:
WIPO Patent Application WO/2021/052240
Kind Code:
A1
Abstract:
The present invention relates to the related technical field of laser probe component analysis, and provides a laser probe classification method and device capable of automatically selecting spectral lines on the basis of image features. The method comprises the following steps: (1) acquiring a plasma spectrum of a sample, and imaging the plasma spectrum to obtain a spectral image; (2) extracting image features and image feature coordinates of the spectral image, and converting the extracted image feature coordinates into actual wavelengths of analytical lines according to linear correspondences between the image features and the actual wavelengths of the analytical lines; and (3) extracting spectral intensity of the analytical lines, constructing a classification model by combining the obtained intensity of the analytical lines with a classification algorithm, and then classifying, by means of the classification model, a product to be classified. The present invention improves the classification efficiency and the classification precision, has a high automation degree, and can effectively avoid human factors while improving the line selection efficiency.
